As of August 27, 2026, Lexis AI is best understood as a search path to Lexis+ with Protégé. LexisNexis says it renamed Lexis+ AI in February 2026. The current product combines legal research, drafting and analysis workflows; Protégé is the assistant that powers those workflows and also appears across other LexisNexis products.
That naming distinction matters in procurement. A historical review of “Lexis+ AI,” a demonstration of Protégé and a quote for Lexis+ with Protégé may refer to related but different scopes. Put the exact product, market, features and contract date in the evaluation record.
Naming crosswalk
| Name | Current meaning | Buyer consequence |
|---|---|---|
| Lexis AI | Common search term and informal shorthand | Confirm which product and date the speaker means. |
| Lexis+ AI | Former product name, according to LexisNexis | Treat older reviews and screenshots as historical. |
| Lexis+ with Protégé | Current US legal drafting, research and analysis product | Request a quote and feature scope for this named product. |
| Protégé | AI assistant used within Lexis+ with Protégé and other LexisNexis surfaces | Do not assume every Protégé capability is included in every subscription. |
What the current product page says it does
LexisNexis describes workflows for full-document drafting, conversational legal research, document analysis, citation checking, reusable skills, shared Workrooms and access to organization materials. It also describes Shepard’s Verify as a way to check citations in responses, documents and drafts.
These are vendor-reported capabilities, not independent findings about accuracy or time saved. The product page also describes customer-data controls and says customer data is not used to train public models or improve performance for other customers. Procurement still needs the operative agreement, security documentation, configuration and subprocessor terms.
The workflow test that matters
Avoid evaluating “legal AI” in the abstract. Select a matter-shaped task with a known answer and review boundary.
| Test field | Record before the test | Record after the test |
|---|---|---|
| Task | A narrow research question, draft section or document analysis | Whether the product completed that same task |
| Source set | Authorities and matter documents allowed for use | Sources actually cited or relied on |
| Reviewer | Named lawyer responsible for final judgment | Time spent checking authority, omissions and language |
| Stop rule | Missing source, unsupported proposition or prohibited data | Whether the stop rule was triggered |
| Baseline | Time and defects under the current workflow | Difference in time, rework and material defects |
A good demonstration is not the same as a successful pilot. A pilot should preserve prompts, source links, output versions and reviewer corrections so the team can explain why it accepted or rejected the workflow.
Questions for the vendor
- Which capabilities are included in the quoted package, and which require another module or content subscription?
- Which sources can ground a response, and how does the interface distinguish Lexis content, organization content and the open web?
- What does Shepard’s Verify check, and what remains for the lawyer to validate manually?
- How are uploaded documents retained, deleted, permissioned and logged?
- Which model providers and subprocessors can process matter data under the proposed configuration?
- Can administrators restrict features, models, data sources and sharing by role or practice group?
- What happens to Workrooms, skills and audit history at termination?
Evidence boundaries
The official pages support the naming change and the presence of described workflows. They do not establish a universal accuracy rate, a privilege outcome, a guaranteed reduction in review time or a universal price. Commissioned studies and customer stories should remain vendor-reported even when prepared by a third party.
For confidentiality and professional responsibility, map the proposed workflow to applicable client terms, firm policy, state rules and later guidance. ABA Formal Opinion 512 is useful general guidance under the Model Rules, not a substitute for jurisdiction-specific review.
FAQ
Is Lexis AI discontinued?
LexisNexis states that Lexis+ AI was renamed Lexis+ with Protégé. That is a product evolution and naming change, not evidence that every historical feature or contract automatically maps to the current package.
Is Protégé the same as Lexis+ with Protégé?
No. Protégé is the assistant. Lexis+ with Protégé is the legal product that combines the assistant with LexisNexis content and workflows.
Does Shepard’s Verify eliminate citation review?
No. The vendor describes it as a citation-checking capability. The responsible lawyer still needs to open the authority, confirm the proposition, jurisdiction, treatment and factual fit.
Is there a public monthly price?
The current product page says pricing is customized. Buyers need a current quote tied to their users, content access, workflows and contract terms.
